flutter 可滚动警报对话框顶部的固定容器

我需要将内容固定到可滚动警报对话框的顶部。我试着用几种方法来做到这一点，但我只设法使对话框的所有内容都可以滚动。第一个视频显示了它是如何发生的今天和第二个显示或多或少我想发生的事情，但与不同的是，固定的部分必须在顶部。
为了解决这个问题，我使用了操作，但操作总是在警报对话框的底部，我真的需要它在顶部。我将提供视频，以便更容易解决问题：
如何（应该是最高固定信息）：

如何使用操作将信息固定在底部：

代码：

有人能帮我吗

在使用scrollable: true时，它使内容可滚动，包括title。在AlertDialog内容中使用ListView，创建约束问题。您可以在上面使用LayoutBuilder并根据需要提供约束。

showDialog(
  context: context,
  builder: (context) {
    return LayoutBuilder(
      builder: (context, constraints) {
        final width = constraints.maxWidth;
        final height = constraints.maxHeight;
        return AlertDialog(
          title: Text("Top Part"),
          content: SizedBox(
            width: width,
            height: height,
            child: ListView(
              children: List.generate(
                33,
                (index) => SizedBox(
                  height: 100,
                  child: Text(index.toString()),
                ),
              ),
            ),
          ),
        );
      },
    );
  },
);

另一种方法是在SingleChildScrollView中使用Column on

showDialog(
  context: context,
  builder: (context) {
    return AlertDialog(
      title: Text("Top Part"),
      content: SingleChildScrollView(
        child: Column(
          children: List.generate(
            33,
            (index) => SizedBox(
              height: 100,
              child: Text(index.toString()),
            ),
          ),
        ),
      ),
    );
  },
);
